` TO ALL WHOM IT MAY CONCERNK;

Be it known that I, ANDREW BARCLAY WALKER, of Warrington, in Lancashire, and Kingdom of England, have invented new and useful Improvements in Apparatus for Brewing, Malting, Distilling, and Drying; and I do'hereby'deolare that the following is 'a' full, clear, and exact description thereof, which vill enable those skilled in the art -to make and use the same, reference beingl had to the accompanying drawings, forming part of this specification.

My improvement has for itsspccial object the facilitating ofthe process of brewing and distilling by attemperating the atmosphere in the gyle-tun rooms, or the atmosphere immediately surrounding the gyle-tuns, or

attemperating the worts by a dircctapplication of the air to the saine, to that degree of. temperature in summer or winter hy which lthc process -ol vinous fermentation may be most successfully conducted, never allowing Y the temperature to risc above or fall below that degree of temperature, during which the azotic constituents of the worts become most speedily oxidized hy theoxygen of the atmosphere; and further, the maintenance of that degree of sentability or uniformity of temperature throughout the process of fermentation. In the accompanying sheet of draivingsv 4 I l v Figure 1 represents a plan or top view of my improved means for attemperating atmospheric air-and con'- dncting the same directly to the Worts inthe gyletuns.

Similar letters of reference indicate corresponding parts.

A represents a box or vessel, of rectangular or other proper form, constructed' of tinned copperA or other suitable material. l

Within this box or vessel I fix a tube o'r series of tubes, a, passing from end to end, and communicating nith chambers, b b', at their ends, as shown more particularly in g. 6*.

Through this box or vessel, A, Icause a, constant supplyof spring-water to ow, by means of alpump or otherwise, or I ll the vessel with ice, orice and common salt, or other salts or acids, or salts land acids combined.

Through the tube or tubes a in the vessel, I force atmospheric air by means lof a pump or pumps, cylinder or cylinders, fan orfans, or bellows.

The atmospheric' air is. thus cooled or attemperated by passing throughthe tube or tubes a, surrounded v with the Water or freezing-mixture or mixtures. The natmosphericair thus cooled or attemperated, I conduct, from the vessel by means. of a pipe or pipes, I3, to the place required.

In figs. 1 and 2, this cold airis shown conducted by the pipes B ldirectly over the gyle-tuns C C, a rose or douche, D, projecting from a pipe, B, directly over the yeast or worte' in each gyle-tun, so that a shower of cool air will be discharged over the surface ofthe yeast or worts.

During the williger season the natural temperature ot`"the air will be sufiiciently low to render the use of the attemperator unnecessary, and the air may be impeiled directly through the pipe or pipes B. l

In iig. 3, a modification of the above plan is showin vThe gylc-tuns are constructed with njacltet or outer case', E, with a space between, provided with herizouf tal partitions ata suitnbledistance apart, to form chambers, c, which communicate one with another by open ings, d, made consecutively at`opposite sides ot' the gyle-tnns. The cold airis admitted into the upper chamber c, and traverses around the gyle-tun through the several chambers, and is discharged at e.

In `g, C, a p lan is shown for preserving theyeast 'in thc receivers or troughs.

EX is thc'yeast-trough, into which the yeast passes from thc punchcons F by the pipes j', B being the pipe from the attemperator or fan. y,-roscs orkdouches, for distributing the .air over the surface of the yeast. A

In`iiig. 5, a modification of this plan is shown, E being the yeast-trough, into which the yeast passes from the puncheons F. p

B, pipe frompthe attemperator'o.' ian, and g', roses'or douches for distributingv the air over the surface ot the yeast.` i Y i In figs. 7 and S a planis shown for regulating the temperature of the atmosphere in the inalting-rooms- G represents the malting-rooin. B, pipes fdr conducting aii"`i`rom attemperator or fan. t, roses or douches for discharging the air over the malt on the iioor, or discharging into the room.

Instead of the roses or douches, the pipes B may be perforated with small holes, for discharging `the air into the room. v 4 i l By placing the attemperator over the furnace, the air may be heated and forced into and through a room for drying malt, hops, and other substances, (see fig. 9.)

A modification of theattemperator illustrated in figs. 1, 2, 1, and G is shown in figs. 10, 11, and 12.

In this modification, one-half, 'or any proper number of the tubes ofthe attemperator are placed in ahinged frame, A, which is attached to and forms a part of the atteinperator, or thei'rame, instead-0f being'hinged to the box of the' attemperator, may b e otherwise arranged, so that its tubes may be set within said box and liited bodily out therefrom.

.The box I of the attemperatorin this case is provided with tubes, 2', the ends ofwhich communicate with chambers, j,- to form a sinuous route or passage for the air or duid, as shown clearly in fig. 10, c being the indueA tion and Z the eduetiontnbe. The tubes .an in'the frame II, when the latter is adjusted on the box ofthe attenua perator, fit between the tubes z' in the box. rlhe tubes m communicate near their" ends vwith tubes iz. 1t in such a. manner as te admit oiwa si'nuous route or passage for the air or fiuid through the tubes m..

By this arrangement two separate and distinct passages are obtained, the worts being in the spaces between the tubes, cold air being forced through ene set of tubes, and a frveezingmixture.through the other set, the worts being in the space between the tubes, er werts may be forced throughone set of tubes and cold air through the other, a freeziiigmixti1rc being passed through the box ofthe attemperator.

I claim as new, and desire to secure by Letters Patent-f- 1. The general construction and arrangement of the apparatus for attemperating air, as described, and illustrated in figs. 1, 2, 4, and G of the accompanying drawings.

2. The construction` and arrangement of the apparatus for preserving yeast or worts in gyle-tuns, as described, and illustrated in figs. 2 and 3 ofthe accompanying drawings.

3. The means. employed for preserving yeast in the troughs or receivers, :is described, and illustrated in figs. 5 and 6 ofthe accompanying drawings.

4. The construction and arrangement ofthe apparatus for attemperating the atmosphere in inalting-rooms,

. gyle-tnn rooms, cellars, 88e., de., as described, and illustrated in fig. 7.

5. The construction and arrangement ot` tbc apparatus for cooling works, as described, and illustrated in gs. 10, 11, and'12I ofthe accompanying drawings.

The above specification of iny'invcntion signed by me, this 25th day of February, 1868.

ANDREW BARCLAY` WALKER.
